Question

Evaluate C(8, 8).


0

1

n

8

Answer 1

Answer: Second Option

C(8,8)=1

Explanation:

We must calculate a combination

The combination
`C (n, r) =(n!)/(r!(n-r)!)`

Where n is the number of elements that you can combine and you choose "r" from them.

So

C (8, 8) is the combination of 8 in 8.

Therefore

`n = 8\\r=8`

`C(8,8)= (8!)/(8!(8-8)!)\\\\C(8,8)=(8!)/(8!(0)!)\\\\C(8,8)=(1)/(1*1)\\\\C(8,8)=1`

The answer is the second option
